Insert a wall anchor if needed. Then screw the carbon steel base into the anchor until the plastic washer presses against the mirror or glass. Finally, snap or thread the polished stainless steel cap onto the exposed screw head – it should sit flush against the washer. No visible hardware left.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cstrong\u003e🔧 What size cap should I use for my mirror?\u003c\/strong\u003e\n\u003cp\u003eLarger caps (30mm–40mm) are meant for heavy commercial mirrors or as a design statement. For typical home bathroom mirrors (up to 40 lbs), 20mm–25mm caps work perfectly. The cap diameter is purely decorative – the actual screw size is standard. Pick a cap that looks balanced with the mirror thickness and your decor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cstrong\u003e💧 Are these rust‑proof for bathrooms and showers?\u003c\/strong\u003e\n\u003cp\u003eThe stainless steel cap is fully rust‑resistant – fine for high humidity. The carbon steel screw is hidden behind the cap and washer, so moisture rarely reaches it. However, if installing inside a steam shower or direct water spray, we recommend adding a tiny dab of silicone sealant over the screw head before capping for absolute protection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cstrong\u003e🔧 Can I use these on glass panels or acrylic mirrors?\u003c\/strong\u003e\n\u003cp\u003eYes – the plastic washer is designed to prevent glass‑to‑metal contact, which reduces the risk of cracking. For acrylic (plastic) mirrors, even safer. Do not over‑tighten the screw; snug is enough. The washer should just kiss the surface.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-faq-item\"\u003e\n\u003cstrong\u003e🧼 How do I clean the stainless steel caps?\u003c\/strong\u003e\n\u003cp\u003eWipe with a soft damp cloth and mild glass cleaner or soap. Avoid abrasive pads or acidic cleaners (vinegar, bleach) – they can dull the polished finish over time. If you notice fingerprints, a microfiber cloth restores the shine.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-note\"\u003e💡 \u003cstrong\u003ePro tip:\u003c\/strong\u003e For a seamless look on frameless mirrors, measure the distance from the wall to the mirror surface – the cap should fully cover the screw head plus washer. If the washer is too thick, the cap may not snap on all the way. Use a thin plastic washer (included) or stack two washers for deeper clearance.\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"M12 (Cap Dia.12mm) \/ 2
